I’ve read a lot about DNS and how exactly the entire website address lookup works, but I am confused.
Here is my setup, the domain is not example.com, I’ve just changed it in the picture, but it follows the same pattern as the real one:
These were automatically added after a Cloudflare scan of my domain before I used Cloudflare, and I’ve not changed them.
First, what is the A record with ‘*’, how does it work? Do I need it? Cloudflare warns me it exposes my IP address.
And what records do I need to change to use the CNAME flattening service, so I can increase the speed of DNS resolving? CNAME can’t point to an IP address, so if I add a CNAME ‘example.com’ what do I point it to? And do I delete the A record ‘example.com’?
Also, can I get the mail to work via Cloudflare? I remember reading that’s impossible and I should use an email service hosted elsewhere instead, but I am not certain.
Unfortunately, I can’t do trial and error to figure this out myself, as people might lose access to the website.
